She was immediately inundated with comments from followers calling her out on her apparent attack on Faryal, with one replying that her New Year's resolution would be "trying not to break up families and break up family ties".

Another said, "try to make up with your brother", while a third wrote: "try not calling my sister in law a 'rat' and acting like a little jealous girl. A hard one but good resolution".

Mariyah, 19, had earlier this week shared another post that many thought threw shade at Amir and Faryal.

She had posted a picture of their other brother, Haroon Khan, with his partner Arifa, captioning it: "Happy one year anniversary to this beautiful couple! Alhamdulillah my brother couldn't have got a better partner."

Manchester Met Uni student Mariyah had also reportedly commented on a critic's page after the unnamed commenter called the Khan family "cruel".

In response, Mariyah wrote: "Babes she doesn't allow us to see her [Amir and Faryal's daughter Lamaisah]."

The feud started when Faryal posted a 'naked' selfie on her Instagram – and Amir's Muslim parents were allegedly disappointed to see their daughter-in-law wearing very little clothing.

Faryal then took to Snapchat to blast her inlaws, claiming that she was being abused by them.

That was followed by Amir's father Sajjad Khan branding her "very evil" and hinting divorce could be on the cards for the couple.

"She is trying to come between us, she is trying to break up the very close relationship we have with Amir. She is a very evil woman," he said, according to the Daily Star.

"I have given and taken with her. We all have. All she wants is the limelight."

In response, Faryal's own parents, Shaukat and Zia Makhdoom, sent an impassioned plea to their son-in-law not to start divorce proceedings.

"We have hearts, hearts that are broken when we hear such things. We are living in fear that at any moment our daughter will get divorced," said Faryal's mother.

"Please accept the girl as your own daughter. And please don't say such a word to any girl, to anyone's daughter.

"We are parents too. We are living in fear that at any moment our daughter will get divorced. May they always live happily."
